For the second consecutive year, no minorities were nominated in any of the four acting categories. One year after the critically acclaimed "Selma" was largely snubbed by academy voters, sparking protests, actors and filmmakers of color are again being ignored -- and Twitter is not happy.

"It's actually worse than last year. Best Documentary and Best Original Screenplay. That's it. #OscarsSoWhite," tweeted April Reign, an editor who was credited with launching that hashtag in protest after last year's nominations were announced.

Idris Elba had been expected to score a nomination for his performance as an African warlord in "Beasts of No Nation," but he was passed over. Other hopefuls such as "Concussion" star Will Smith, "Creed" star Michael B. Jordan, that movie's writer-director, Ryan Coogler, and the cast of N.W.A biopic "Straight Outta Compton" also were ignored.

The best original screenplay nomination noted by Reign went to the co-writers of "Compton" -- both of whom are white.

Again, #OscarsSoWhite (and #OscarsStillSoWhite) was trending on social media, with some people noting the irony of black comedian Chris Rock presiding over a February 28 ceremony in which no minority actors are honored.

It's actually worse than last year. Best Documentary and Best Original Screenplay. That's it. #OscarsSoWhite

Such complaints ebbed somewhat in recent years, as movies with largely black casts such as "The Help," "Lee Daniels' The Butler" and "12 Years a Slave" won Oscar recognition.

But protests flared anew last year when the civil rights drama "Selma," despite widespread praise for director Ava DuVernay and star David Oyelowo, was nominated only for best picture and best original song.

If you're counting, that's 40 Oscar nominations these past two years for actors -- all of them white.

As cultural critic Mark Harris noted, this marks the first time there have been no black acting nominees two years in a row since 1997-1998, so maybe it represents a dip and not a pattern.

"The older, white, male votership doesn't hate women, gays, black people. They're just not as interested in their/our stories," Harris said Thursday on Twitter. "That's changing, as the membership changes. A good year can disguise the fact that they have a way to go. A year like this lays it bare."
